Objective To evaluate the result of staged arteriovenous shunts for the treatment of thromboangiitis obliterans(TAO) and arterial sclerosis obstruction (ASO). MethodsData of 176 cases undergoing this procedure were retrospectively reviewed. ResultsIn this group, 147 cases (83 5%) were followed up with a median of 9 8 years. Pain and/or claudication disappeared in 86 out of 90 cases (95 5%) treated by low positioned shunt one week postoperatively, with a limb salvage rate of 100%. Among 57 cases treated by high positioned shunts of the lower limbs, pain and claudication disappeared in 43 cases (75 4%) 2~3 weeks postoperatively. Postoperative amputation has to be performed in 5 cases with a limb salvation rate of 91%. ConclusionsThe clinical result of this staged arteriovenous shunts is satisfactory for the treatment of thromboangiitis obliterans(TAO) and arterial sclerosis obstruction (ASO).

Objective To investigate the mechanism of Sini San Formula in the treatment of ulcerative colitis and depression through"homotherapy for heteropathy"based on network pharmacology and molecular docking.Methods The TCMSP database was used to obtain the potential active components and their related targets;GeneCards,CTD,and TTD databases were used to screen the disease-related targets of ulcerative colitis and depression;the intersection of the predicted targets of the active components and the disease-related targets was used to obtain the potential targets(shared targets)for the treatment of ulcerative colitis and depression by Sini San Formula,and Cytoscape 3.7.2 software to construct a"Chinese medicinals-active components-diseases-common targets"network to analyze the core components;importing the common targets into the STRING database,constructing a common protein-protein interaction(PPI)network.The GO function and KEGG pathway enrichment of the shared targets were analyzed by DAVID database,and molecular docking between the core components and the key targets was verified.Results A total of 136 active components of Sini San Formula were obtained,and 220 potential targets of action(shared targets)for the treatment of ulcerative colitis and depression by Sini San Formula,involving 657 biological processes,70 cellular components,147 molecular functions and 133 signaling pathways.The screening yielded core active compounds such as quercetin,kaempferol,lignans,naringenin,7-methoxy-2-methylisoflavone,key target proteins such as JUN,MAPK3,STAT3,AKT1,and MAPK1,as well as signaling pathways such as TNF,IL-17,Th17 cellular differentiation,HIF-1,and Toll-like receptor.Five potential key targets have strong binding activity to quercetin,kaempferol,lignans and naringenin.Conclusion Sini San Formula may act on key targets such as JUN,MAPK3,STAT3,AKT1,MAPK1,etc.through active components such as quercetin,kaempferol,lignocerotonin,naringenin,etc.,and play the role of"homotherapy for heteropathy"for ulcerative colitis and depression through the signaling pathways such as TNF,IL-17,HIF-1,Toll-like receptor and Th17 cell differentiation.

Objective To analyze the effect of different environments risks on the prognosis of patients with chronic obstructive pulmonary disease (COPD). Methods A total of 231 patients diagnosed with COPD who visited Mianyang Hospital of Traditional Chinese Medicine from April 2018 to January 2021 were selected as the study subjects and divided into two groups according to whether the residence was changed after discharge, that is, Mianyang Environmental Living Suzhou Environmental Living Group. The follow-up time was 2019 December to September 2021. The contents include relative humidity, temperature, PM_2.5, PM₁₀, air quality index, exposure to household smoking environment, and open windows for ventilation. The regional environment was mainly measured three times, namely October to February (expressed as cold period), June to August (expressed as warm period), March to May and September to October (expressed as suitable period). The family environment was followed up every 2 months by means of questionnaires and interviews, and detailed records were recorded. After the follow-up, the COPD Assessment Test (CAT) and Modified Dyspnea Rating Score (mMRC) were analyzed. Concentration-response curves were used to analyze the influence of living environment exposure on the prognosis of COPD patients. The generalized additive model with semi-Poisson distribution as the connection function was used to study the influence of univariate and multifactor environmental factors on COPD. Results The air quality index of Mianyang was higher than that of Suzhou during the cold period, while that of Mianyang was lower than that of Suzhou during the suitable period. Meanwhile, the average relative humidity of Suzhou was higher than that of Mianyang during the warm period. The comparison of CAT and mMRC scores of COPD patients in the two regions in different quarters showed that the CAT and mMRC scores of COPD patients in Mianyang City were lower than those in Suzhou City during the cold period, and the difference between groups was statistically significant (P<0.01). PM_2.5 (warm period), PM₁₀ (warm period) and NO2 (suitable period) increased by 10μg/m³, 8μg/m³, 12μg/m³ and CO (suitable period) increased by 0.3mg/m³ respectively caused COPD function The scores of indicators CAT and mMRC increased. After adjusting for other pollutants, PM_2.5, CO were still related to the prognosis of COPD. Concentration-response curve results showed that the risk of increasing CAT score decreased with increasing daily windowing time; conversely, the risk of increasing CAT score was increasing with increasing environmental exposure to smoking. Conclusion Pollutant exposure and living environment factors have a significant impact on the prognosis of COPD, and improving the environment is of great significance for the recovery of COPD pulmonary function.
